I'm experiencing a very odd graphical glitch with the code editor, initially I thought it was my machine's graphics going to pot but after further investigation it is definitely tied to Xcode and/or my project file.
This glitch appears to follow my project around, I have tried deleting derived data and userdata from the project folder, I've also made sure all of my fonts are the same (this was suggested in another thread for a similar sounding issue). Very often while editing code the below graphical error occurs, it is very frustrating. Has anyone else encountered this?
I've moved the project across multiple Macs and the problem persists, I would be really grateful for any insight on how to prevent this as I'm nearing the end of a very long project and this has pretty much put a halt to progress.
Thank you!

I've found a workaround that works for me until an official fix is provided. The glitch will still be happening but just during build and not while coding.

Have anyone tried out the new Color Asset Catalogue feature in Xcode 9. For me every time I edit something on this like adding or editing a colour asset, I have to wait for 10-15 seconds while Xcode shows the coloured progress and does not allow any interaction.
At the same time being highly annoying, it is also highly counter-productive. I also found IB to be generally too slow after updating to Xcode 9.
Are these known issues ? Is there a solution to this?
i asked apple about the hangs and crashes that keep on occurring on Xcode 9, and they replied:
First, quit Xcode. And then temporarily move aside
UserInterfaceState.xcuserstate so that new user state is created.
It can be found here
path_to/$WORKSPACE.xcworkspace/xcuserdata/$USER.xcuserdatad/UserInterfaceState.xcuserstate
(if it is an .xcodeproject, it will be deep in the project.xcworkspace
directory).
this worked for me with autocomplete problems and switching between files. hope it helps you out as well.
Xcode 9 is borderline unusable for me too at times. The worst is how long it takes to open/edit a storyboard file and also run the simulator. Even autocomplete and switching between code files is lagging a lot for me, much more so than past versions. I imagine Apple knows about it considering the Apple development forums are full of threads about how the newest update is unacceptable but as for how long it will take for them to do anything about it, who knows. It's an absolute nightmare for iOS developer's productivity to say the least.
My solution is to just quit Xcode when it starts getting too slow. It's a pain, obviously, but usually helps short term.
There is a question here about this already (though,short of re-installing Windows, which I'm obviously trying to avoid, the other solutions don't work for me), but I have some research to add, and a possible solution... which I don't understand, but perhaps someone here is able to shed light on how to implement it? I'm using Visual Studio 2015 Community on Windows 10 Pro x-64 with Anniversary Update (and latest cumulative update).
There is a possible work-around - details at https://social.technet.microsoft.com/Forums/windows/en-US/2f51398c-cef2-4686-9505-904d3f71ef6d/windows-10-applocker-packaged-app-white-list-blocks-store?forum=win10itprogeneral - where the resolution is to allow all Windows App Store apps, however no steps are given, so I don't know how to do that.
There is a relevant hot fix at https://support.microsoft.com/en-gb/kb/2719305, however that is targetting an older version of Windows, so I'm not sure of the repercussions of trying that. I'm leaving that as my last resort short of re-installing.
And finally, there is re-installing, as per the other thread on here, as the Anniversary Update is considered the suspect (and I'm past the rollback window). I already had the AU when I first tried UWP, so I never had it working to begin with to know if this is the culprit or not. I have never touched applocker myself (had never heard of it) - I have this problem out of the box.
Apart from the time involved, I don't want to re-install as there has been mixed success with it - for one person it fixed it, for another it fixed it initially but the problem came back. I am trying to get a permanent fix (and only re-install if I can't find one).
Anyone know a permanent fix for this? Or how to implement the first suggestion? Or implications of the second?
P.S. for the sake of completeness (and to pre-emptively answer this question), one of the things I already tried is the MS trouble-shooter for this issue (I think I found this one on MSDN from memory). It suggested using my MS login instead of my local user, and to change the temp environment variables back to default (I had them pointing to RAMdisk), but doing those things failed to fix the issue.
Well, I ended up re-installing Windows, having corrupted it along the way, and that ended up fixing the issue. I found along the way that the problem actually stops ALL apps from the store installing (I never did find out how to implement the store fix I mentioned in my question), and that provides a quick way to see if the problem is fixed (rather than trying to build/deploy your UWP app each time you think you've fixed it, just try installing a store app).
I did find something that MAY be a solution, at https://answers.microsoft.com/en-us/windows/forum/windows_8-winapps/this-app-wasnt-installed-error-0x80073cf9/92ec7c44-51ef-4c6a-9331-22958e01b4ec?page=1, which relates to how to recover from a corrupted user profile (I'm not being allowed to upload a snapshot of the relevant reply due to still being relatively new here. Sigh) - which I now believe to have been the cause - however I didn't get to try it out as I'd already corrupted Windows at that point. Note that none of the other solutions in that thread worked for me, so I would start with this one first, as the other solutions only worked for some people. If you have this problem then I would try that first before re-installing.
P.S. at one point it looked like the Anniversary Update may have caused the problem, however after I re-installed I tried before applying the AU, and then again with the AU, and it kept working afterwards,so that was NOT the culprit. It was the user profile/Windows being corrupt.
I've Googled around a bit on this issue and haven't been able to come up with anyone else having an issue to this one, so a) I apologize if this is a known issue; and b) I'm thinking this proves that I must be doing something horrifically wrong, yeah? :-)
My application has a very rich landing page which is the first page that is shown after a new launch. It has a panorama control, a large background image (but much smaller than the 2000x2000 limit) and recurring and ongoing animations. Prior to updating my tools to the January refresh, this page ran relatively smoothly. After updating and running the app in the emulator, the background of this page is white (despite the fact that the emulator is on the "dark" theme), performance is quite poor (both in terms of swiping through the panorama and in terms of my recurring animations). When I run the same project on my device, all is well (since, quite obviously, my device's OS is not on the updated image).
Clearly I must be doing something grievously wrong to merit such a cataclysm, but I'm not sure what it might be. I've tried disabling bitmap caching in the places where I'm using it, removing third party tools I'm using such as Peter Torr's awesome tilt effect and his memory usage counter, and several other hail-Mary-style moves, and the problem remains. I also looked through the provided resources and change log to see if perhaps something related has changed, but I didn't see anything.
I'll try to provide example code later if it would be of any use to any would-be saviors out there, but the app is pretty complex and large in terms of lines of code and file size, so it might be a bit tricky. i just thought I'd toss this out there and see if anyone might happen to see it and think of an obvious solution.
Thanks so much in advance for your time and help.
P.S.: I cross-posted this question on the official WP7 dev forums. Sorry if that's against the rules - I'm not a regular SP-poster, as you can tell. If it's a problem, let me know and I can delete the other post.
I was ultimately able to resolve this by creating a brand new project using the updated tools and copying my code, assets, and relevant project settings into it. The app now runs flawlessly on the emulator (or, at least, the flaws in it are my flaws and not the emulator's :-)).
I believe I originally created the project on an earlier version of the SDK, so maybe I had some kind of invalid or incorrect project settings. If I get a moment later, I'll compare the project files to see if I can identify a setting or difference that explains the disparity.
Thanks to all who looked (and to Matt, who even responded :-)). I'll report back if I have any more information that might be of help.
UPDATE: Updating for anyone who might be having this issue as well - my resolution above was a false positive. Creating a new solution and copying stuff in does indeed work, but only until you save and close the new solution. Upon reopening, the problem recurs. Grrrr. I'll post back if I come up with anything else.
Ever since I started using Xcode, I've experienced extremely annoying problems with Code Sense. The problem is that when Code Sense kicks in for code completion, sometimes the source code text below the line I'm working on goes "crazy". If I continue typing, the problem gets worse, and after a while the source code is completely screwed up (funny colors, missing lines and characters, ...). Strange enough, the source code itself is unaffected, because when I select another source file and then go back to the one I was working on, everything looks fine again.
The problem can be seen in this screencast: http://www.screencast.com/t/OGY3NWE5
Interesting facts:
This problem has occurred on 3 different machines, so it's not related to a corrupt installation.
Sometimes it's fine for a while (up to one hour) after launching Xcode, but once it starts happening, it's getting worse and worse, until Xcode is restarted. Then it's fine again (for a while)
I've searched the web for similar experiences, and I can't find anything. I would think that it is a known problem, since it occurs on 3 different Macs here (both running 10.5 and 10.6).
Anyone having the same problems? Or a suggestion for fixing this?
Yeah, it can be a real pain. I didn't find a 'fix for it as such, but I do a quick switch from implementation to header (or vice versa) and then back again using Command-option-up. The screen redraws and everything is fine again
Well, I finally (kind of) fixed this problem by simply turning off Quick Help. Previously, I left this on all the time, and it resulted in a very unstable code sense (to the point where Xcode simply became unusable).
This is not a real solution, but it should at least help people experiencing the same issue.
I wrote about it here
My issue was with localization. if your XIB file is localized using xcode 4's, then it was failing for me. removing the localization worked, though not a proper solution.
In one customer computer (windows vista) almost all forms of my app are oddly unnaligned.
Making some investigation I noticed that every component with akRight anchor acts oddly, being positioned way more for the right.
Searching in SO I found this issue wich is similar to mine but not exacly the same.
Since I cannot reproduce the issue in my computer and my access to my customer´s computer is restrict to a few minutes and via remote desktop I´d like to know if my issue described here could be solved by the same fix.
Aren't you experiencing the problem described in the following question?
Why do my Borland C++Builder 5 forms with right-anchored controls appear incorrectly on Vista?
Maybe the answer is of some help.
I've also experienced similar issues. After much frustration I pretty much gave up using anchors and started using a combination of the Align, AlignWithMargins and Margins properties.
