**Description**  
My approach was to design a User interface that collects Username and Meeting No. I have written some lines to Initialize SDK, Authenticate and parse params to join meeting but nothing seems to work when I tap join meeting. Please help.

**Which version?**  
5.0.24433.0616

**Smartphone (please complete the following information):**  
Xcode Simulator

**Additional context**  
This is what my code looks like:

**MyAppController.h**

//

// MyAppController.h

#import \<UIKit/UIKit.h\>

#define kSDKDomain @ “[zoom.us](http://zoom.us)”

NS\_ASSUME\_NONNULL\_BEGIN

**@interface** MyAppController : UIViewController

//- (void)joinMeeting:ViewControllerNo withUsername:(NSString\*)meetingUser;

**@property** ( **weak** , **nonatomic** ) **IBOutlet** UITextField \*MeetingNumber;

//@property (weak, nonatomic) IBOutlet UITextField \*MeetingName;

**@property** ( **weak** , **nonatomic** ) **IBOutlet** UITextField \*Username;

//@property (weak, nonatomic) IBOutlet UIButton \*BackToFrontNavigation;

**@end**

NS\_ASSUME\_NONNULL\_END

**MyAppController.m**

//  
// MyAppController.m  
//

#import “MyAppController.h”

Hi @Tobiak,

Thanks for the post. Could you provide an SDK log for us to further investigate this issue? When the issue happens, terminate the app and wait for a few seconds and then fetch the log.

Thanks!

I have successfully initialized SDK in my Project’s AppDelegate.swift this way;

**import** MobileRTC  
…  
…  
let context : MobileRTCSDKInitContext = MobileRTCSDKInitContext.init()  
context.domain = “[zoom.us](http://zoom.us)”  
context.enableLog = true  
MobileRTC.shared().initialize(context)

And created ViewController.m (OBJ-C) and collected join meeting param (with storyboard User Interface).

At the moment, app is able to join meeting using the frameworks found in this download " ios-mobilertc-all-5.0.24433.0616-clientlog" (Emulator and Real Device).

But when I replace those frameworks with the ones from this download link below:

“[https://github.com/zoom/zoom-sdk-ios/archive/master.zip](https://github.com/zoom/zoom-sdk-ios/archive/master.zip)”,

my app freezes at launch screen. See screenshot added:

 ![Signalbrt error](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/f/fd12630e2044193655a2fc81b708718953edd87d.jpeg)

App target is iOS 11  
Xcode Version 11.5

**Frameworks added to project:**  
MobileRTC.framework  
MobileRTCScreenShare.framework  
MobileRTCResources.bundle

Kindly help please.

I solved this already.  
So I did the following under Target \> General \> Frameworks,Libraries and embedded Contents:

Changed MobileRTC.framework and MobileRTCScreenShare.framework to “Embed and Sign”

Also at Target \> Build Phases \> Link Binary with Libraries  
Changed the above frameworks to “Required”.

There is still a problem however. This is the list of errors show when trying to distribute to Appstore:

**App Store Connect Operation Error**  
Invalid Mach-O Format. The Mach-O in bundle “Myapp.app/Frameworks/MobileRTCScreenShare.framework” isn’t consistent with the Mach-O in the main bundle. The main bundle Mach-O contains arm64(machine code), while the nested bundle Mach-O contains armv7(machine code) and arm64(machine code). Verify that all of the targets for a platform have a consistent value for the ENABLE\_BITCODE build setting.

App Store Connect Operation Error  
Invalid Bundle Structure - The binary file ‘Myapp.app/Frameworks/MobileRTCScreenShare.framework/MobileRTCScreenShare’ is not permitted. Your app can’t contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at [https://developer.apple.com/go/?id=bundle-structure](https://developer.apple.com/go/?id=bundle-structure) for information on the iOS app bundle structure.

App Store Connect Operation Error  
Invalid Info.plist value. The value for the key ‘MinimumOSVersion’ in bundle Myapp.app/Frameworks/MobileRTCScreenShare.framework is invalid. The minimum value is 8.0

App Store Connect Operation Error  
The binary is invalid. The executable ‘Myapp.app/Frameworks/MobileRTCScreenShare.framework/MobileRTCScreenShare’ has type ‘OBJECT’ that is not valid. Only ‘EXECUTE’ is permitted.

App Store Connect Operation Error  
The binary is invalid. The encryption info in the LC\_ENCRYPTION\_INFO load command is either missing or invalid, or the binary is already encrypted. This binary does not seem to have been built with Apple’s linker.

App Store Connect Operation Error  
Missing load commands. The executable at ‘Myapp.app/Frameworks/MobileRTCScreenShare.framework’ does not have the necessary load commands. Try rebuilding the app with the latest Xcode version. If you are using third party development tools, contact the provider.

Hi @Tobiak,

Thanks for the post. Regarding the issue you are facing, please try the following:

1. In the build setting of your broadcast extension, please set `Bitcode` to NO. Or you could use `lipo` to decouple the `MobileRTCScreenShare.framework` into an `arm64` only framework. The framework includes both `arm64` and `armv7`.
2. Set the `minimumOSVersion` in the `MobileRTCScreenShare.framework/Info.plist` to be 8.0. We will enhance this part in the next release.

Hope this helps. Thanks!
