I never had a problem building with Meteor and XCode before, but after upgrading to Meteor 1.4.2.3 with React I'm getting a whole lot of build issues. XCode has asked me if I wanted to upgrade to Swift, but I've been reluctant afraid that it may stop previous builds from other projects from working.
I converted to swift, but I still am having many errors although less then before. Is there an easy fix for this?
Apple have upgraded to xcode 8 now and that has caused all kinds of problems with new versions of swift which are not compatible. This is the case in many areas not just meteor projects. The meteor webapp has been updated to allow for this so I would recommend that you go to xcode 8 as well.
Given that meteor generates all of the code you shouldn't need to worry about compatibility

I abandoned a project I was working on for a while I came back to open it on upgraded flutter and dart plugin in visual studio code windows 10.now I get so many problems. is there a way to automatically update code to solve these errors?
do these steps:
delete build folder
delete .idea folder
run flutter clean
run flutter pub get
run flutter pub upgrade
then try to run your project.
The simple answer is it depends.
Judging by the comments from a reasonably good answer by Hasan Abbasi, this wasn't enough.
Depending on how old your project is, there are 2 choices before or after doing what that answer said:
If it's any more than 2 or 3 years old, I'd probably rewrite it from scratch. In that time, Flutter and Dart have matured greatly, which involves many breaking changes. Also, null-safety has been introduced. Creating a new project after updating Flutter will also fix those Gradle issues because the configuration files will be reset.
If it's less than that, try to fix those Gradle issues either by hand or just deleting the '/android' or '/ios' etc. folders and letting Flutter/Dart automatically recreate them when you run the app next. You'll probably need to migrate to null-safety: read about null-safety so you understand it properly, then try using the dart migrate tool. You will likely need to spend some time changing dependencies for null-safe versions. Then you can try the flutter fix tool to automatically resolve SOME issues.
Hope you can get your app to work soon!
so I build up an app with React Native (v 0.64). And I made up ios build using Xcode (version 12.3). The app gets build and works without any crash or bug - on simulator and also on real iPhone (latest iOS versions 14.3).
Despite working everything fine, I get during buildtime a LOT of warnings (196). Mostly they are of a two kinds- Nullability issue or Deprecations.
I got all my node modules updated to latest versions and I think the podfile is okay too. But the warnings appear at almost every library I am using, so it makes me assume that I am missing some more general point (maybe wrong podfile or something like that). What I am missing?
I am about to publish on App store in next days (after working several weeks on this project) and this makes me worried so much. I attach screen from the Xcode of mentioned errors (part of those). Any help would be much appreciated in advance. Thank you.
I'm currently using xCode 5.1 and Objective-C to learn how to make apps and I'm wondering what would happen to my projects if I update from 5.1 to 6. Will my projects still run or will I have to code everything in Swift?
Your projects should still run if they were running in previous versions. What will most likely happen is that you will be bombarded by warnings and alerts about deprecated code and syntax. You're going to get a lot of them with an upgrade that big.
For the most part, XCode should tell you exactly what needs to be upgraded. It shouldn't change any of your code. But it's always good practice to back up your project.
Good luck!

Trying to get some solid documentation on how to get the iPhone emulator in Xcode running with my PhoneGap 2.1.0 project. I pulled it down from a git repo that I originally built on my Mac Pro, now want to run it on my Mac Air. There is a lot of confusion of the terminologies between PhoneGap and Cordova that make it near impossible for a beginner to figure out how to set up a project.
The problem I'm getting when I open my PhoneGap project in XCode is this error:
Lexical or Preprocessor Issue 'Cordova/CDVViewController.h' file not found
Clearly the Cordova class files aren't being seen by XCode, although I included the path to the CordovaLib classes in Preferences -> Source Trees (~/Documents/CordovaLib/.
Just want to get this thing running! Thanks!
Not sure if this will help you, but I am starting to try to get to grips with PhoneGap/Cordova, and found this excellent guide on getting it going.
It uses Cordova, which I am led to believe is the source of PhoneGap (Still SLightly Confused tbh), hopefully it will help you in one way or another, it certainly got me up and running :)

I wonder whether I should start development of a new iOS project in Xcode 4 or 3.2 - on one hand, I know 3.2 (a little), there is lots of info about it out there, and it's stable and proven. On the other hand, Xcode 4 brings some improvements as well. Are the newer previews of Xcode 4 ready for prime time, or are they still too buggy?
I'm especially interested in issues with (and recommendations of) externally hosted repositories, as I was not very happy with how Xcode 3.2 played with the Subversion repository in my last project.
Which one to choose, and which (preferably free and externally hosted) repository to match?
Today (3rd Feb 2011) Apple released the GM-Seed of xcode4. It's now ready for usage and you can compile your apps and release to the app-store. So if you are new with xcode, I would suggest using xcode4.
Why?
The new compiler has a lot of optimizations done. The compiler (as far as I can see the results) generates faster code. It's big fun!
The new Userinterface is more reliable. It makes your development a lot faster!
2a. Interface builder is now integrated. You can "drag and drop" your userinterface Item using the "ctrl"-key into your code and xcode creates the source for you! This accelerates creation of userinterfaces a lot!
git support has been added to sourcecontrol, which makes development in teams easier
The new LLVM compiler shows errors immediately while coding. And it displays errors, which xcode3 never mentioned
In xcode4 Apple changed a lot! So if you start with xcode3, you will have a new learning curve with xcode 4. For newbs I suggest: Download the xcode4 goldmaster and get startet with xcode4!
I second JackPearse's endorsement of Xcode 4, with one caveat. Been using Xcode 4 for a couple of days and am really starting to like it. Particularly like the way it shows the changes in each file as you commit. Unfortunately, when you delete a file, it forgets that it will need to be deleted in the repository as well. But the big BUT right now is that Xcode 4 will immediately crash the moment you try to do any Core Data modeling. See also XCode 4 Data Model Versioning bug? here on Stack Overflow. So, if you plan to use Core Data, you'll need to keep Xcode 3 around as well until they fix this.
