Since I've updated to Xcode 8.1 I can't archive and also not run in Release mode (in debug mode its working). The error is that there are several "duplicate symbols for architecture arm64" and all are "duplicate symbol __TMRbBp". Whats that?
This question is related to
xcode8.1
I had similar issues with Version 9.2 (9C40b), the solution is
0) Close Xcode
1) Open project folder in terminal
2) pod update
3) open .
4) open project by clicking Project.xcworkspace
I faced the same problem with archiving on Xcode 8.1.
X Code Version: Version 8.2.1 (8C1002)
The following fix worked on Mar 2019
1) Go to Project & Select your Project
2) Select Build Settings -
Search for "Enable Bitcode" Set option as "NO"
3) Most of version will fix this issue, for few other XCode version try this option also,
Search for "Reflection Metadata Level" Set option as "NONE"
I had removed files from Compile Sources in Build Phases in Targets. I added main.m
and it worked.
Had the same problem in Xcode 10.1 and was able to resolve it. In path Project Target > Build Setting > No Common Blocks
, I changed it to No
.
In my case
Problem Solved
Don't double click Project.xcodeproj to start your xcode project. Instead, close your project and open the xcworkspace.
File -> Close Workspace
File -> Open -> Search your project folder for Project.xcworkspace
All my errors are gone.
1.Close your project:Completely quit Xcode. 2.Go to your project location:there you will find two files in you root folder with varying extensions: Appname.xcodeproj and Appname.xcworkspace
Now open your project by Double clicking on file with the extensions xcworkspace.(***Appname.xcworkspace*)**
Yourproject will open in xcode. Now run your project again.
If you pay close attention when installing your pods,firebase makes it clear to open your project with your-project.xcworkspace after installing pods firebaseIOS Setup
$ cd your-project directory
$ pod init
Add to Podfile
pod 'Firebase/Core'
And finally:
$ pod install
$ open your-project.xcworkspace
Dont forget to add firebase to your AppDelegate
For those that can't get the Thorax's answer to work, what I did was I closed out Xcode, ran pod update
on my command line and then reopened the .xcworkspace file. After doing that, I was able to build and run the project.
I am using the Firebase Cocoapod and Xcode version 9.1.
Surprisingly, in some occasions, simply cleaning the product worked for me.
Quick fix to try before looking at other solutions.
If you're using Ionic and the Push and Console plugins that's the problem. Remove the cordova console plugin (which is deprecated) and the error will disappear.
The linker error is saying that a library is duplicated which is, in fact, true because the console plugin is already in cordova-ios 4.5+
It took me a couple of hours to figure this out!
close you project then open xcode go to file -> open search your project and open it . this worked for me
I got this error due to deletion of some files. For me simply cloning my project worked.
I ran into this problem recently creating a new project and adding some pods (AlamoFire specifically) to the project. Troubled with it a couple hours or so recreating the project (it was new) several times. Tried all the methods here and no luck.
Eventually I figured out that it was because XCode V10.1 was also opening the old project file along with the new pod-created workspace when I opened the workspace via command line "open myProject.xcworkspace" when I reopened the project after doing "pod install"
Closing all projects before exiting XCode before I did my "pod install" fixed everything for me.
