Realm-cocoa: Any stable version for Swift 3?

[Luccifer]

Hello! Wondering about RealmSwift with support and the full power of Swift 3d generation, but:

I tried to use Pods with
pod 'RealmSwift', :git => 'https://github.com/realm/realm-cocoa.git', :branch => 'jp-xcode8-ci'
and failed on installing with output:

[!] /bin/bash -c
set -e
sh build.sh cocoapods-setup

core is not a symlink. Deleting...
Downloading dependency: core 1.5.0

ERROR: One of Realm's submodules is missing!

If you're using Realm and/or RealmSwift from a git branch, please add 'submodules: true' to
their entries in your Podfile.

Realm version: Latest

Xcode version: 8.0 (8A218a)

iOS/ version: 9.1 +

Dependency manager + version: CocoaPods stable version

[steveatinfincia]

Add the submodules argument, like this:

pod 'Realm', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true

pod 'RealmSwift', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true

[bdash]

As @steveatinfincia mentioned, you need to let CocoaPods know that Realm's Git repository uses submodules. This will let you build Realm Swift from our master branch.

To answer the question in your title: we intend to make a release next week that includes support for both Swift 2.3 and Swift 3.0. Until that release we may make some small changes to our Swift 3 API to better fit with the changes to the Swift naming guidelines.

This is what I get:

$ bundle exec pod install --verbose

platform :ios, '10.0'

target '****' do
  use_frameworks!

  pod 'RealmSwift', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true

And Xcodeproj from the master for Xcode 8 object version

I've followed the steps adding bot pods with master branch and submodules and I get these errors:

/MyProject/Pods/RealmSwift/RealmSwift/Realm.swift:478:46: @escaping attribute only applies to function types
/MyProject/Pods/RealmSwift/RealmSwift/Migration.swift:180:57: @escaping attribute only applies to function types

Any idea on how to fix it?. When is the "real" version released? Monday?

[bdash]

@puttin, you must explicitly specify both Realm and RealmSwift as dependencies when using a version of RealmSwift from Git. If you don't then CocoaPods will attempt to satisfy the Realm dependency with the most recent Realm release, which isn't necessarily compatible with RealmSwift from master:

pod 'Realm', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true
pod 'RealmSwift', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true

@bitomule, are you using the Xcode 8 GM seed build (8A218a)? We made changes on master to be compatible with it earlier this week, which quite likely broke support for the earlier beta versions of Xcode 8. If you're not using the GM seed, please update and try again. If you are using it, please file a new issue with more details about what you're doing to see this.

[puttin]

@bdash It turns out my fault. I delete Xcode 8 beta 6 this morning but forget to update xcode-select to GM version.

[bitomule]

@bdash thanks! using GM worked.

In order to get Swift 3 versions of Realm and RealmSwift, I had to explicitly target master, set submodules to true, _and_ include a post_install hook to set the Swift version:

use_frameworks!

target 'TARGET_NAME' do
    pod 'Realm', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true
    pod 'RealmSwift', git: 'https://github.com/realm/realm-cocoa.git', branch: 'master', submodules: true

    post_install do |installer|
        installer.pods_project.targets.each do |target|
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '3.0'
            end
        end
    end
end

[arshadsk5]

Hello ,
i wanted to use realm swift framework for my swift 3 project, can any one please let me know which version to be used.

@arshadsk5, please don't comment on old, closed issues. File a new issue, or ask your question on Stack Overflow.
