I am a beginner in iOS app development. I am currently working on a project that needs to be changed from Parse to Firebase`.
I installed cocoa pods and "firebase/core" pod as firebase site instructed.
Imported firebase.h in appdelegate.h
Added [FIRApp configure]; in 'didfinishlaunchingwithoptions'
Added 'googleservice-info.plist' in project.
After doing these steps, I ran the build but it failed with following errors (Screen Shot)

I know this has something to do with the parse code in my project but I don't have much knowledge in Parse or in Firebase.
Please help me with this error and guide me how to successfully migrate from Parse to Firebase.
If you used Parse SDK, just make sue you delete ParseFacebookUtils.framework library from your project or from your podfile remove
pod 'Parse'
pod 'ParseFacebookUtilsV4'

Recently I've decided to integrate GCM to my project that already uses Google Protocol Buffers. Everything worked fine, sample was OK. But when I've tried to integrate GCM via CocoaPods to my project - I started receiving build errors:

I've assumed that this is because GCM library has ProtocolBuffers in it and it is conflicting with my Protobuf sources that I've got from here:
https://github.com/google/protobuf/tree/master/objectivec
I've also tried to build for the device and as a result receive similar error - with armv7 instead of x86_64. Also I must say, that sample project works fine, so I think that Protobuf is that main issue here.
Still, I have no idea how this could be resolved. Any thoughts?
Check if the architecture of libGcmLib.a and your target build architecture are the same.
You can check the architecture of .a file with command
otool -hv libGcmLib.a
Apprarently following objects are not built against x86_64 architecture.
GCMSecureSocket.o
GtalkCore.pb.o
...
How do you build libGcmLib.a static lib ? Review it.
I have an app where first time I used PARSE. Then for second update, client requested GoogleMaps . When setup GMS, it said: " Choose your project, rather than a specific target, and open the Build Settings tab. In the Other Linker Flags section, add -ObjC. If these settings are not visible, change the filter in the Build Settings bar from Basic to All. "
If I set -ObjC to linker flags, I have this kind of errors from parse:

ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)
I found a solution to do not add Facebook in app and to use this kind of flag: -force_load
And after using this, I have also error: ld: file not found: clang: error: linker command failed with exit code 1 (use -v to see invocation)
I tried different types of using this, like : -force_load - the same error -force_load pathOfFramework/ - the same error
It is possible to give me a solution for this ?
Thanks a lot !
The problem is that parse has classes that it doesn't load if it doesn't need. For example, it only imports the Facebook classes if FacebookSDK is installed. -ObjC loads all of these, but they are dependent on FacebookSDK. When it can't find the files it needs, it throws errors:
Change:
-ObjC
To:
-force_load $(PROJECT_DIR)/GoogleMaps.framework/GoogleMaps
Source: Here
So On the simulator It works all perfect. No errors, nothing
Now I want to put it on my iPod and I get some unknow errors and I dont't know how to fix them.
-I have the MediaPlayer.framework and it is included in my build
Here is the error:

Can anyone tell me what the error means and what I have to check? :)
Thanks
The only thing whcih is understandable for me is: unsupported file format.
It can't find the MediaPlayer.framework I believe is the problem. You need to update your Library Header Search Path in the build settings. It is looking for it on your desktop I believe.
You may need to add it to your target, relink it, or just make sure its pointing in the correct place.

For the undefined symbols, you need to add libz to the linked libraries. See: error when import zlib in iphone sdk
