Hi I'm new in iOS development and using xcode 7.2 and swift as programming language. I'm working on integration of Google API to send mail programmatically. When i run project in simulator it works perfectly but if i run it in actual device it throws the error
dyld: Library not loaded: #loader_path/../Frameworks/GTL.framework/GTL
Referenced from: /private/var/mobile/Containers/Bundle/Application/9EC87076-4ACC-464A-AA7F-5133EF51F946/AppName.app/AppName.
After changing setting in Targets->General->Linked Frameworks and Libraries-> GTL.framework -Required to Optional, the error goes out but while running app it crashes with error
NSForwarding: warning: object 0xcab20 of class 'GTLServiceGmail' does not implement methodSignatureForSelector: -- did you forget to declare the superclass of 'GTLServiceGmail'?
2016-02-15 23:38:49.579 AppName[675:190073] *** NSForwarding: warning: object 0xcab20 of class 'GTLServiceGmail' does not implement doesNotRecognizeSelector:
How to solve this problem? Please guide me.
Thanks in advance.

I am integrating Facebook Login & Sharing into a game for IOS using Unity. But as soon as app launches i am getting this error
-> applicationWillResignActive()

Actually I got almost same error codes in my project on Swift. So is not problem Unity, is problem connection Facebook SDK to project.
In my case, this error happened, when I try use VPN application Luna. Is seem have conflict VPN with Facebook SDK if is connected to project not correct. When VPN disabled, application and analytics worked without any problem.
For fix my problem, in "Project->Build Settings" need have parameter "Other Linker Flags" value "-ObjC".
Also I used bridge ".h" file for connect Facebook SDK to my Swift project. I had line "#import <FBSDKCoreKit/FBSDKCoreKit.h>", so I delete it from bridge. And manual added in every Swift class, what used Facebook SDK this line:
import FBSDKCoreKit
I did not have the "FBSDKCoreKit" parameter in "Other Linked Flags". Adding the package, then cleaning the build was a fix for me
I built a Unity project using Vungle ads and when I build the project for iOS and try to run I get a NSInvalidArgumentException in a Vungle Network Manager call. Does anybody know how to solve this?
This is the error:
Uncaught exception: NSInvalidArgumentException: -[VNGNetworkManager configOperationWithBackgroundInit:complete:]: unrecognized selector sent to instance 0x129ee6110
Turns out it was a bug with the Vungle lib.
Adding GameController.framework to General -> Linked Frameworks and Libraries and -ObjC flag to Build Settings -> Linking -> Other linker flags fixed the problem.
I've just recently started working with Xcode, trying to build iOS version of our Unity3D game that is already made for Android. The problem I'm having occurs when trying to start my app in Xcode simulator, tried to find my exact problem in here but nobody is mentioning "__vtcOnSessionStart". Full error message:
dydl: Symbol not found: __vtcOnSessionStart

For some reason I'm getting this in the iPhone Simulator when I try to call AddComponent on a script-created GameObject during another object's Awake() method. Removing this fixed the error.
Jumping off of this facebook/react-native#1626 GitHub issue, I had a question about setting up a React Native view within an iOS share extension
I posted an example GitHub repo that demonstrates the problem, summarized below.
So far the proof-of-concept setup is pretty straightforward, but I feel like I'm missing something very simple.
In my react-native init scaffolded Xcode project I created a new Share Extension target, and within it linked the appropriate React Native static libraries (libReact.a, libRCTWebSocket.a, etc.). This gets our project compiling for a very simple ShareViewController that's a plain ‘ol UIViewController.
Upon activating my Share Extension from another app, my ShareViewController is initialized but immediately crashes with the following log messages:
2015-11-29 12:44:34.721 [warn][tid:com.facebook.React.JavaScript][RCTContextExecutor.m:129] 'undefined is not an object (evaluating \'RCTWebSocketModule.connect\')'
2015-11-29 12:44:34.726 ShareExtension[66473:2179009] -[RCTBatchedBridge redBox]: unrecognized selector sent to instance 0x7fb59d8ab200
2015-11-29 12:53:47.160 [warn][tid:com.facebook.React.JavaScript][RCTContextExecutor.m:129] 'Requiring module "InitializeJavaScriptAppEngine" which threw an exception'
2015-11-29 12:53:47.160 ShareExtension[66473:2179009] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[RCTBatchedBridge redBox]: unrecognized selector sent to instance 0x7fb59d8ab200'
The line 'Requiring module "InitializeJavaScriptAppEngine" which threw an exception' looks particularly suspicious, and leads me to believe that I'm missing some basic JavaScriptCore setup within the share extension. Curious to know if there are any obvious areas to investigate, or if anyone else has solved this problem. Thanks!
I had the same error and fixed it by adding "-ObjC" in my app extension target build settings (Other linker flags)
I've been getting reports of my app crashing on load in iOS 6. It's built with the iOS 8 SDK and works fine on 7 & 8.
I've just managed to get hold of an iOS 6 device to test and it does in fact crash on launch with the error:
dyld: Symbol not found: _UITransitionContextFromViewControllerKey
Referenced from:
/var/mobile/Applications/895BC1B3-A362-42C9-8560-5CF40A682A10/myapp.app/MyApp

/var/mobile/Applications/895BC1B3-A362-42C9-8560-5CF40A682A10/myapp.app/MyApp
I understand that dyld is a linker problem, but have no idea where to start with this.
I've unlinked and re-added UIKit, but still doesn't work.
Thanks
This is because UITransitionContextFromViewControllerKey doesn't exist until iOS 7. Working around this probably isn't worth the effort--it means dropping all usage of UIViewControllerContextTransitioning, as the protocol is new in iOS 7, or creating a separate code path for iOS 6. If that's what you want, look into weak-linking UIKit, although this may result in slow startup.
Look like your using UIViewControllerContextTransitioning. It's available only on iOS 7+.
