Necessary to clean every time when building with XCode 4? - xcode

As the title states, if I don't clean my project before building, neither the simulator nor the iPhone is able to get my most recent code changes. Has anyone else experienced this problem or does anyone know of a fix?

Yes. Although I haven't experienced it a lot. Plus its recommended. If you watch iPhone Dev Videos taught at stanford by Alan Cannistraro (One of the Apple engineer's who worked on Cocoa Touch framwworks) recommends doing that.

Once I upgraded versions, this problem went away on it's own. It must have been a bug or a configuration issue of some kind, so I'm marking this as answered.

Macbook Air doesn't load my React App

I have a very strange question, and I apologize in advance for the vagueness. I have a react app that seems to work on all machines that I've tried it on except macbook air computers from 2014 through 2016. This seems very strange to me, so much so that I don't know how to boil down the question on why there is a problem much further than that. Is there a known bug or something else that is going wrong that would cause this to be an issue? If anyone who has a macbook air, or may be interested in seeing the bug, the repo for my site is here: https://github.com/patientplatypus/professional_portfolio_retrofuturism. Please let me know if you have any thoughts. Thank you very much.

Xcode 6.3 Simulator Apple Watch detects feel in a different place

I have a very strange problem with Apple Watch simulator in Xcode 8.3
The problem is with clicking buttons. The simulator detects feel completely in a different place than it is the button. Does anyone has the same problem?
Regards,
Mateusz
UPDATE: This is fixed in the latest betas.
Go download it from the Apple Developer Center.
Couple of things hereā€¦
First off, Xcode 8.3 is still in beta, so you're technically not supposed to be discussing things about it here. Instead, use the official Apple Developer Forums. Apple's own developers frequently respond to questions there, so it's a great resource. Take advantage of it.
Second, there's really not much we can do about it this. It's a bug. If you're having troubles, let Apple know, not us.
File a radar at bugreport.apple.com. When more developers report a certain bug, it gets its priority raised, which prompts Apple to fix it sooner.
See this article for more details.
To benefit us all, be a good developer citizen and file radars whenever you find a bug.

Apple does not like the file XIB in xcode project

I've read around the net that Apple does not like the use of multiple XIB files in Xcode6 project. Someone experienced in this thing can 'confirm whether these "rumors" are true or false?
Sorry for the stupid question but I thought to ask here on stackOver saw the large number of experienced iOS developers
Apple doesn't care about your internal app structure. This is total nonsense.

If I install phonegap, will I have problems with Xcode in the future?

I am an engineer but I don't have any development background. My boss gave me a Mac Mini with Xcode in it, and looks like someone sent me some source code to be used with phonegap.
So my question is, if I install (?) phonegap, will I be able to use Xcode in a normal way in the future, or is it an irreversible process that changes Xcode completely?
No, it will not affect Xcode at all. Now, you will just be able to select the phonegap application type when creating a new Xcode project if that is what you want to use.
I suggest you to have a look on that, under "Phonegap Generate" : http://savagelook.com/blog/portfolio/8-things-to-know-about-phonegap
And on that too : https://groups.google.com/forum/?fromgroups#!topic/phonegap/VE9EiD-eIrY
why So Serious,
You can user the xCode as is since the moment you intalled phonegap.
Do not panic and enjoy coding.
Thanks,
Jigar
Oh yes! If you install it you will be lost forever :D Just joking! Go on!
Nothing wrong will happen, consider take a look at the documentation before start doing things...

Upgrading to Xcode 4.2 produces a lot of SudzC warnings

I'm working on an iOS App and I'm using SudzC to interface with a web service.
It works great, but under Xcode 4.0 it would give me three warnings. Two of them I was able to fix and the third I didn't figure out but I figured I'd come back to it later before my project was done.
A few weeks back I upgraded to Lion and Xcode 4.2. Now there's a whole lot more warnings on the exact same code. I've gone in and resolved some but others I'm not yet skilled enough to know how to fix. Also we modified the web service so this is code I've recently re-generated, so I don't think it's the fault of the SudzC site (I've been generating it through the website)
Has anyone else had this experience with SudzC and Xcode 4.2? Do you just ignore the warnings? Suppress them? Fix them? Is there something I'm doing right/wrong?
