I've been working on a lightweight game with some friends. Today I updated Unity to 2018.1.0f2, and after about 30 minutes of loading time, I was able to edit my project again.
But all of a sudden, Unity is being very slow. I try playing the game, and it is running at about 2-3 FPS. The current editor mode is DX11, but I tried forcing it to OpenGL and that only made it much worse. My computer should be able to handle it; I have a GTX 1080, 32 GB of RAM, and an i7-8700K.
Can someone please explain what is causing this, and how to fix it?
Also, there is a known bug involving Unity collab being slow. I am not using that.
I'd try two things:
1) Uninstall all Unity installs you have (2018 and earlier, if you still have them), then re-install 2018.1.0f2 from scratch.
2) Go to your project folder, and delete everything except the dirs Assets and ProjectSettings (you may delete even this one, but then you need to re-set all project settings from scratch) - remember that if you imported packages via NuGet, you should leave the Packages directory too.
Then try to relaunch Unity and load the project by opening it from the Unity launch window and see if it lags again or not.
Let me know how this goes.
I'm having some trouble working with xCode. It just keeps hanging and using 100% CPU right after a couple lines of code. I'm working on a new project and it barely has two files and it has become completely imposible to work with.
I tried reinstalling xCode and starting my project from scratch but it won't work.
I noticed three things that may help someone find out what it's going on.
It's slow even when typing, the characters appear delayed on the screen.
It keeps saying indexing on the task bar on top. If I clean the project it will disappear but come back whenever I start working again.
It overheats as soon as I open xCode
And here's some other facts that might help
I'm running xCode 6.1.1 (build 6A2008a)
My Mac is a mid 2012 MacBook pro 8GB Ram
I did a fresh install of Yosemite a month after it was released, so it's pretty clean.
I'm using the latest build of Xampp for my SQL server
I'm using nodejs as a backend so I'm running an http with nodemon
Hope any of you has a solution to this.
Thanks and merry christmas to all of you.
EDIT
I found out that it will build just fine if I remove my conditional cast to NSInteger, NSString, Float, etc. I have like 8 of them one after the other, and just replacing as? for as did the trick. I'm curious as for why this is happening anyway though.
Similar problems on 6.1.1 (but also source kit crashes) were improved (but not completely resolved) for me by deleting derived data.
I'm having weird issues with Xcode. I am trying to install the new Xcode 6 from the Mac App Store, but it got stuck at "4 minutes remaining".
Earlier I had Xcode6 GM which was working perfectly fine. I thought of downloading the new version from the App Store so I deleted the GM.
Did anybody else have the same issue?
I had the same problem.
Forgive the cliche, but I had to "turn it off, then on again" (reboot the MacBook) and only then could I re-click on the "Install" button, and it'd start downloading XCode, from scratch.
Previously, using the App Store "Check for unfinished downloads" just told me that I didn't have any downloads pending, yet in the App Store app, it had XCode stuck in the "Installing" state.
Update
It's that time again. iOS 8.4 has been released, but you can only get XCode to connect to an iOS 8.4 device if you've upgraded to XCode 6.4... but you can only do that if you've upgraded OS X to the latest version. Thanks, Apple.
And as usual, download times are appalling, even if (like me), you've waited a few weeks until after the release, to avoid the rush.
And when you finally do get to click on the Update button in App Store to update XCode, it changes to "Installing" but actually, it's busy spending the next few hours downloading, rather than installing anything.
You have to keep an eye on the download bar, just below the Launchpad icon on the taskbar, to check how far the painfully-slow download has got...
I'm really not impressed.
I quit App Store, then searched for XCode in my Applications folder, clicked it, after a few seconds the download status vanished and I was able to click it again and open the app.
If it's any help, I was in Software Update this morning updating to Xcode 6.2. For several minutes, the installer was also stuck at the 4 minutes remaining mark, and then started changing the time remaining (swapping between longer and shorter intervals). From what it looks like, this is a UI issue (probably not estimating all the time it takes to install all components), more than anything else...
After clicking Install on Xcode in the App Store I got a busy-indicator in the App Store window for a few seconds and then nothing, it still just read "Install" after leaving it sit overnight.
However, I was able to download the latest version of Xcode as a .dmg file at https://developer.apple.com/downloads. The installation process was smooth from there.
In App Store, try "Store" menu -> "Check for unfinished downloads..."
I had a similar problem. Mine was stuck on "Paused". To fix it, I went to "Applications" (command-click the old version in dock -> gets you there faster) and moved to trash the Xcode app that was 337 kb in size. Then rebooted, went to the App Store and started the installation again. Turns out mine was "paused" on 2.27 gb (though I simply left my mac unattended, since the download was taking forever, and returned hours later).
Hope this helps someone, as I could not find an answer to this myself anywhere else.
I got the same problem. I updated to the last version of OSX, and then the update came automatically as a a result of that update.
I have stuck many times, this saved me. Now you try your luck on this
Apple should really consider having some more indication of install progress. Hard seeing any progress with the bar alone when installations exceed a certain amount of time. But then again I see apples security considerations indicating more detailed logging of the progress. I guess they oversee the few situations when updates are in the gigabyte range.
It may seem like a cancellation of the install , and going on for a second time, gives a faster install. But I would guess thats only because some of the install progress is cached.
My tip is; wait it out.
i have an app that when i run on xcode connects with the database and retrieves the required values PERFECTLY.
But when i run the actual application in the Debug folder, it not only does not access the database , it also does not go into any of the functions in my code.
Why can an application show this type of behaviour? It never happened before to me. I have an old copy of the code which works fine. I have clear the targets and built it like 10 times but still runs perfectly on xcode but the app individually isnt quite working..
Thanks in advance for any help .
I am out of ideas and i have no direction to go to as from a programming perspective the code does its work.
memory management issues... be sure to remember [database release] instead of autorelease which works fine on the xcode but crashes the app in mac os
I have an Xcode project that has been upgraded to Xcode 3.2, and whilst it builds fine (and produces an executable that runs fine), when I try to debug it the debugger doesn't start.
When I look in the debugging window, it says that the build was fine. When I look in the console, I get a 'Session started ', but the application never begins.
I've had a wander through the build settings, and can't see anything that appears to be turned off when it should be turned on. I thought it may be a new setting that I need to turn on, but I can't see anything of interest that may help.
Any advice would be grateful accepted!
Cheers and thanks.
Have you tried a full Clean of the project?
I was having the same problem and just discovered that my app launches on the iPhone correctly when I've started Xcode from the finder, but not when I've launched Xcode from my shell. For example, I start Xcode by typing "open project.xcodeproj" into my bash terminal, and device debugging is broken, but if I start Xcode via spotlight or by double-clicking on my project, or from the Applications folder, device debugging works fine. I'm not certain, but it appears to be a problem with my shell environment variables.
Thanks to Rob for the advice. I tried rebuilding everything a couple of times and still to no avail.
However, after turning on my machine this morning, trying the project out it now debugs quite happily. I'm guessing that after installing Xcode I should have rebooted the machine (it didn't require one according to the installer).
Thanks all.
