Realm-cocoa: Umbrella header 'Realm.h' not found

[augard]

Goals

Install Realm using Cocoapods 1.0

Expected Results

I expect it to install and work as per the instructions on https://realm.io/docs/swift/latest/

Actual Results

Umbrella header 'Realm.h' not found

Steps to Reproduce

Add Realm to podfile, run pod install and build project

I tried to clean Pods with
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
pod install

From pods realm project file, it looks like it's failing to set Realm.h header as public in Pods.xcodeproj, so it's failing to build module map.

Code Sample

platform :osx, "10.10"

inhibit_all_warnings!
use_frameworks!

target 'Project' do

pod 'CocoaLumberjack'

pod 'Sparkle'
pod 'HockeySDK-Mac'

pod 'Realm'

pod 'AFNetworking'
pod 'AFNetworkActivityLogger'

end

Version of Realm and Tooling

Realm version: 0.102.0

Xcode version: 7.3.1

iOS/OSX version: 10.11.4 (15E65)

Cocoapods version: 1.0

I can't reproduce this using the same configuration of tools you have here. Could you please try the following and share the console output?

pod cache clean Realm
pod cache clean RealmSwift
pod deintegrate || rm -rf Pods
pod install --verbose

Looks like there may have been some changes in the last few CocoaPods 1.0 RC's that actually broke Realm support in some cases, I'm hunting down exactly what those are for now, or if I'm doing something wrong, because I think I was able to reproduce this. I'll keep you posted.

[BarlowTucker]

I had a similar issue and was able to resolve it by cleaning the build folder.
(Hold down option while clicking Product in the Xcode menu shows the Clean Build Folder... option)

I hope that helps.

[MarkPolivchuk]

I'm also having this issue. Cleaning build folder didn't help.

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

target 'My-App' do

    pod 'Alamofire', '~> 3.3'
    pod 'AlamofireObjectMapper', '~> 3.0'
    pod 'XLPagerTabStrip'
    pod 'Kingfisher'
    pod 'DZNEmptyDataSet'
    pod 'RealmSwift'

end

[augard]

@BarlowTucker Thanks, but it didn't work.

[skrenek]

@BarlowTucker's solution above actually worked for me after running the following:

rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
pod install

It took the combination of the two to get it to compile for me.

[MarkPolivchuk]

@skrenek That worked for me. Thanks to you and @BarlowTucker!!

[augard]

@skrenek Sadly, it's not helping me.

[drieran]

Failed for me. I tried all steps and now I'm stucked at this error:

[augard]

@drieran Temporary fix is to change all Realm headers in Pods project Realm directory to public in side panel.

[drieran]

Sorry I'm trying to copy but probably at wrong place. Can you tell me source folder and destination ?

[augard]

@drieran Just go to realm folder in Pods select all .h from Realm and change it to public

[drieran]

No way :(

[drieran]

As mentioned @BarlowTucker Finally, I solved doing that:

So, I am a little ashamed that I didn't try this earlier, but it appears that if I run Clean Build Folder... (Hold down option while clicking Product in the Xcode menu shows the Clean Build Folder... option) it fixes the issue for me.

[mrackwitz]

OS X

We could determine, that there is an actual issue with CocoaPods 1.0, but this is limited to OS X targets. We track this by #3570.

iOS, watchOS, tvOS

If you're building on another platform, please make sure to follow the steps as proposed by @jpsim as seen here:

pod cache clean Realm
pod cache clean RealmSwift
pod deintegrate || rm -rf Pods
pod install --verbose

Please don't forget to clean your build folder as explained by @drieran in the comment directly above:

Hold down option while clicking Product in the Xcode menu shows the Clean Build Folder... option

Note: This can be also achieved via the key shortcut ⌥⇧⌘K.

[huguesbr]

+1 same issue... using Xcode Version 7.3 (7D175).

Try to clean, reintegrate, remove all Pods, reinstall, ...

Unable to make RealmSwift work if I'm using Cocoapods 1.0...

Using pod _0.39.0_ install, fix the issue but it's not really a solution..

platform :ios, '8.0'
use_frameworks!

target 'XXX' do
  pod 'RealmSwift', '~> 0.98'

  target 'XXXTests' do
    inherit! :search_paths
  end

  target 'XXXUITests' do
    inherit! :search_paths
  end
end

[diego-watanabe]

I'm still having a similar issue using cocoapods 1.0.1 and the latest version of RealmSwift. Moving the headers to public doesn't seem to fix the issue for me though.

[collinsmwade]

Confirmed, still having the same issue on cocoapods 1.0.1, building for iOS.

[jpsim]

@collinsmwade @diego-watanabe please file new issues with full steps to reproduce after following the recommendations from our docs.

[PhilippeBoisney]

Same issue on Cocoapods 1.0.1. Doing this do nothing:

pod cache clean Realm
pod cache clean RealmSwift
pod deintegrate || rm -rf Pods
pod install --verbose
rm -rf ~/Library/Developer/Xcode/DerivedData

The only fix I found is to downgrade to Cocoapod 0.39.0. Not the best, but it works..

[jpsim]

@PhilippeBoisney could you please file new issues with full steps to reproduce?

[sunshineclt]

All of the solutions above do not work for me. After trying and trying, I finally found that it is the problem of "User Header Search Paths". At first my user header search paths are $(PODS_ROOT) recursive, which includes Realm，RealSwift and other third-party frameworks. But if I leave the user header search paths empty, it can not work too because other third-party frameworks need it. So I just add other third-party frameworks(except for Realm and RealmSwift) into the user header search paths. Just like that:

Now it works! :)

[mgrider]

Did anyone open a new issue for this problem? If so, I'm not seeing it. I saw it today, and changing the header search paths entry for Realm to recursive was the solution. I definitely believe this to be an upgrade issue, since the project I was working on hadn't been touched since 2014. (Although it's of course possible it's a cocoapods issue, not a Realm issue.)

[Kirow]

Same problem. Made all possible updates/cleans. No luck.
In the end made manual installation w/o cocoapods.

[jpsim]

@Kirow please file a new issue, taking care to fill out the new issue template so we have enough information to look into this for you.

[nhatlee]

All my code in project is written by Objective C, and I install a new library which written by Swift (via cocoa pod), then got the same. I try to remove and install again, then it worked. Maybe Realm-Objective-C conflict with Swift library.

[nadia-am]

i stuck with this error for about a month, none of the above solution works for me! can anyone help me?

[nadia-am]

@BarlowTucker's solution above actually worked for me after running the following:

rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
pod install

It took the combination of the two to get it to compile for me.

it didnt work for me!

This work for me

[nadia-am]

I solved this problem by switching build system:

Open File -> Xcode Workspace Settings
Switch Build System to "Legacy Build System".
