Can't install realmswift 2.10.1 with cocoapods and xcode 9

[westd]

I upgrade to xcode 9 last night and I tried updating my realmswift pod to be swift 3.2 compatible

Goals

install realm with cocoapods 'pod install --verbose'

Expected Results

pod install finishes successful

Actual Results

-> Installing Realm (2.10.1)

Steps to Reproduce

I followed the suggested steps to clear caches several time, but always the result above

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

Realm framework version: 2.10.1

Realm Object Server version: ?

Xcode version: 9.0

iOS/OSX version: 11

Dependency manager + version: cocoapods 1.3.1

[bdash]

The error looks a lot like what happens when the Realm core library fails to download, which the cache clearing steps you mention should resolve. Have you re-tried since reporting this failure?

[Alexander-Foster]

After updating to High Sierra, it is not installed in the same environment

Version 2.10.0 is fine... 2.10.1 and 3.0.0-beta also something wrong

[westd]

Yes I've tried the cache clearing steps above several times and on 3 different networks, always same result. Is there any other debugging steps I can try? What's the link to the core library it's trying to download so I can see if I'm able to download it from here

[westd]

I'm still using macos Sierra by the way. For me the problem started happening when I upgrade to xcode 9

[dungi]

I have the same issues while building RealmSwift with Carthage and Xcode 9

[SlayterDev]

Same issue. Xcode 9 and latest Realm version.

[bdash]

The sh build.sh cocoapods-setup step downloads Realm's prebuilt core binary from https://static.realm.io/downloads/sync/realm-sync-cocoa-1.10.8.tar.xz. The downloaded file ends up at $TMPDIR/sync_bin/sync-1.10.8.tar.xz. We'll use an existing file at this location in the future to avoid unnecessarily re-downloading the file.

Can someone that's seeing this file check if that downloaded file exists, and if it looks to be a valid file? If you run xxd $TMPDIR/sync_bin/sync-1.10.8.tar.xz | head you should see that the first few bytes of the file are fd37 7a58 5a00 (.7zXZ.). You should also see (using ls -l) that the file is 44827356 bytes in size.

[westd]

this is what I see:

ls -la $TMPDIR/sync_bin/sync-1.10.8.tar.xz ls: /var/folders/ml/2x_8p6kx15q3979kssq7s75h0000gn/T//sync_bin/sync-1.10.8.tar.xz: No such file or directory

The sync_bin directory doesn't exist either

[bdash]

Thanks, so you don't have a stale file causing problems. If you wouldn't mind, can you please try the following steps?

git clone https://github.com/realm/realm-cocoa.git
cd realm-cocoa
sh build.sh download-sync

That'll do the same work to download the sync library as is performed when installing via CocoaPods, but without involving CocoaPods. That'll help to narrow down where the problem is occurring.

[westd]

There was no output at all from the last line, and it executed immediately (no sign it was trying to do any actual work)

[bdash]

That's very surprising. One of the first things that the download-sync command does is print out what it is doing (Using version of core already in core/ directory / core is not a symlink. Deleting... / The core library seems to be up to date).

Would you mind sharing the output of which sh?

[westd]

Davids-MacBook-Pro:realm-cocoa dwest$ which sh /bin/sh

[bdash]

Ok, that’s what you should see, but it means I don’t have any idea why it’s failing to download the prebuilt binary. Can you please double check whether a core directory was created inside realm-cocoa by your earlier attempt?

[westd]

there doesn't seem to be any core directory:

Same issue. Xcode 9, Hight Sierra and latest Realm version.

[bdash]

If anyone that's hitting this wouldn't mind spending a few minutes screen sharing with me on Google Hangouts, Skype, or similar, so I can troubleshoot what's going, please drop me a line at mar@realm.io.

[westd]

I sent you an email - we can do it tomorrow some time if you like

[kkrawczynski]

not sure is it related 1:1 but when i use 2.10.1 (Carthage + Xcode 9) then Swift compiler yells that RealmSwift was compiled with Swift 3.1

[bdash]

@kkrawczynski, an issue related to Carthage and Swift versions sounds completely different than the issue being discussed here. Please file a new issue and provide the information requested in the issue template.

[bdash]

I spent a few minutes debugging this on a user's machine. The underlying cause looks to be that our script for detecting which Xcode and Swift version should be used does not correctly handle the currently-selected command-line tools being Xcode's standalone command-line tools (/Library/Developer/CommandLineTools) rather than command-line tools within Xcode itself. Many thanks to Adrian for taking his time to help me look into this.

I'd appreciate some information from others that are seeing this (@westd?), namely the output of xcode-select -p and verification that you're seeing a failure immediately after pod install --verbose runs sh build.sh cocoapods-setup, to help confirm that people are all seeing problems for the same reason.

As an immediate workaround for anyone hitting this issue, you can do sudo xcode-select -s /Applications/Xcode.app to select the command-line tools bundled within Xcode. I'll look to make a more complete fix in Realm.

[bdash]

This should hopefully be fixed in v2.10.2.

[westd]

Is there a work around we can use to get it working before that's released?

[bdash]

v2.10.2 was released a few hours ago. I also mentioned a workaround for v2.10.1 in my earlier comment.

[westd]

Awesome, thanks

[glebus]

@bdash v2.10.2 has solved problem. Thank you!

[westd]

By the way, it didn't work for me 'out of the box', I got this:

Installing Realm (2.10.2) [!] /bin/bash -c set -e sh build.sh cocoapods-setup

WARNING: The active Xcode command line tools, as returned by /Library/Developer/CommandLineTools, are not from Xcode. The newest version of Xcode will be used instead. No version of Xcode could be found

I worked around using your command 'sudo xcode-select -s /Applications/Xcode.app'. Might be an idea to add that command to the error message?

[lidkxx]

@westd sudo xcode-select -s /Applications/Xcode.app is a life saver! ❤️

[LeVanTuan]

@bdash saved my life 💯

[Tr736]

for me the problem was happening because I have multiple versions of Xcode (to support older swift) by simply ensure Xcode is named Xcode in the applications dir resolved the issue

[khirsh]

@bdash Thanks! This problem just happened to me today. I had multiple versions of Xcode and I renamed them "Xcode 9.2.app" and "Xcode 9.3.app". I wonder if the unusual name of the app created confusion for your script. In any case, your solution worked when I used my unusual name of the app:

sudo xcode-select -s "/Applications/Xcode 9.3.app"

In any case, I just wanted to report that this problem still exists in some edge cases.

[parrot88]

'sudo xcode-select -s /Applications/Xcode.app', Danke!

[amrutsaba]

Hi All,

I am using realm 2.10.2 version and i have another library using swift4. When I do POD install, it gives error realm.h not found , if i remove this swift library it builds successfully

has anyone facing similar issue or any solution to this?

Thanks Amrut
