Summary: Swift allows me to import RealmSwift, but it doesn't allow me to create a new instance of the Realm class (or type any code using Realm keywords). I don't have any other code because this is a brand new project.
Steps to Reproduce:
1. Make a new Xcode project
2. In Terminal, cd to the project and type 'pod init'
3. Open the Podfile and add the pod 'RealmSwift'
4. Open the Xcode project's workspace and go to the AppDelegate file
5. Import 'RealmSwift'
6. Make a new variable and make it an instance of the Realm class
Expected Results: The program runs and lets me make a new instance of the Realm class.
Actual Results: The program crashes with the following errors:
Command failed due to signal: Abort trap: 6" & "error: fatal error
encountered while reading from module 'RealmSwift'.
Also, at the top of the file where I wrote the code using Realm keywords, it says:
An Internal error occurred. Source editor functionality is limited. Attempting to restore...
This is a Swift Compiler Error btw
Version/Build:
Realm version: 3.7.4
Xcode version: 4.1
Swift version: 4.1
configuration: MacBook Pro running macOS High Sierra
Have you considered using a Dynamic Framework instead? I did use CocoaPods in the past but using a dynamic framework simplifies the process. Download the frameworks from here:
https://realm.io/docs/swift/latest#installation
And follow the instructions:
After you've dragged the framework into your project, it looks like so:
Now, the hurdle is that since this is not done through pod files, you cannot automatically update the Realm version. This you will have to do manually by downloading the newest version of the framework from time to time.
If you use Xcode packages, you can replace "Up to next major" by the exact version of the package (10.19.0 in my case)

I created a brand new Xcode project in Swift and integrated Ensembles 2.6.2 via Cocoapods.
I also wanted to include Zip compression and Encryption and so I simply added these 2 pods in my Podfile, as suggested in the manual.
Unfortunately after running pod install, I’m getting an error when trying to build. I attach 2 screenshots to give you some context. Unless I’m missing something really obvious, I have no idea on what to try next.
I'm using Xcode 9.4.1 and macOS 10.13.6
I'm trying to integrate swift package manager in my project, but with no luck. The iOS simulator crashes at startup.
Here are the steps that I followed in order to integrate the package manager:
open xcode and create a new xcodeproject: testcpackage
from the terminal I've run the command:
swift package init to create the Package.swift file
swift package generate-xcodeproj
swift build
swift test - everything seems to be ok
open the new generated file testpackage.xcodeproj in xcode
run the application (cmd+R): build succeeded
first error given by the iOS simulator: Could not attach to pid : “9207”
I close the iOS simulator and I run the project again when I get the 2nd error:
No installable items found at /Users/xxxxxx/Library/Developer/CoreSimulator/Devices/555xxx14-xxx-xx-8E6E-C13D5AB463A0/data/Library/Caches/com.apple.mobile.installd.staging/temp.rA1vGO/extracted/Payload
Could you please help me to solve this issue?
I use the following method to get packages to work in iOS. That being said, I'm not sure if this is the "best" way to do this:
Make starting Package.swift file
swift package generate-xcodeproj
Open project in Xcode
Project : Build Settings : Base SDK ==> change to IOS
Editor : Add Target : (iOS ... Single View App)
Select your project, look at target list, find your newly added target : General : Deployment Info
On toolbar, change "active scheme" to the new target
Run
It has worked for me in the past. However, I have had to fix search paths. I'm currently suffering from that problem here: Xcode: missing required module error
Good luck
I'm taking over development of a project and am unable to contact the previous developer. I'm trying to figure out which versions of the imbedded open source libraries were used. The project appears to be in Swift 2.1. I am attempting to compile it with Xcode 7.3.1. Carthage was the package manager used. I'm stuck on an error with RealmSwift. The error occurs on the line that tries to import RealmSwift.
/{app source path}/PersonnelModel.swift:10:8: Module file was created
by a newer version of the compiler: /{app source
path}/Carthage/Build/iOS/RealmSwift.framework/Modules/RealmSwift.swiftmodule/x86_64.swiftmodule
I have worked my way all the way back to version 0.96.2 of realm-cocoa, which I believe is the first version to support Xcode 7.1 and Swift 2.1. However, I'm still getting the error.
I have looked through other answers on here, but have not found a solution that works. Am I misunderstanding the cause of the error? I just thought it was picking up a newer version of the framework.
Here is what my Cartfile looks like:
github "ReactiveCocoa/ReactiveCocoa"
github "Alamofire/Alamofire" ~> 3.4
github "SwiftyJSON/SwiftyJSON"
github "realm/realm-cocoa" == 0.96.2
github "scalessec/Toast-Swift" ~> 1.4.0
If you're just trying to get a clean compile for now, it might be worth taking Realm out of Carthage, installing it manually as a dynamic framework, and then putting it back into Carthage at the end once you've got everything smoothed out.
Xcode 7.3.1 was Swift 2.2. The very latest version of Realm to support Swift 2.2 is version 2.3.0, so I'd recommend downloading that version and manually importing it into Xcode 7.3.1
As an aside, Realm has dropped support for Swift 2 starting with version 2.4.0, so it's greatly recommended you migrate your codebase to Swift 3 as soon as possible. :)
I had this issue today in Xcode 8.3.2 w Swift 3. I mistakenly tried to run the swift 3 converter on one class file and canceled it mid run. Xcode then threw this error for one of my Pods (Bolts). Fix was to remove the pod, run pod update, then add the pod back, run pod update again so the module was reset.
I just started with swift 3 and made a simple app in xcode using Swift 3.0 . Now i want to add a third party library using Swift Package Manager . I am following installation method given in this link . I created Package.swift file which looks like this
import PackageDescription
let package = Package (
name : "SwiftPM",
dependencies : [
.Package(url: "https://github.com/ArtSabintsev/Siren.git", majorVersion: 1)
])
but i get error No such module "PackageDescription"
The Swift Package Manager and Xcode are orthogonal. That is, you can't expect to compile Package.swift in Xcode; it simply won't work. Instead, until Xcode supports the package manager, you need to have two distinct builds - one with the package manager and one with Xcode.
So, using the Swift Package Manager, once you've defined Package.swift and formulated your directory structure as expected by the package manger, you perform simply:
swift build
Then for Xcode, you create an Xcode project that uses your source code, but not Package.swift. You'll need to clone the Siren.git project, explicitly - into your Xcode build's source files.
Swift 3/4
Navigate to your project folder through a terminal and run these commands swift package init --type library first and then swift package generate-xcodeproj
Reference
For me the issue turned out to be Target Membership. I created the Package.swift file manually inside an iOS app project.
Solution:
Select and go to the Package.swift file
Open the File Inspector on the right side
Deselect any modules inside Target Membership section
Refer to the solution in this link:
https://forums.kodeco.com/t/server-error-no-such-module-packagedescription/177438
Command:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
For other people who faced the same error as this:
Fix your Package.swift syntax
I got this error because Xcode hadn't parsed Package.swift fully yet, because of syntax errors.
In my case, I had a .target(name: "name-of-target", dependencies: [""]). As soon as I removed the empty dependency string (""), Xcode immediately parsed the file, and the error disappeared. Remember to save the file though.
Also, GoZoner and Pratiks answers are outdated:
Xcode has integration with Swift Packages now (as shown above)
swift package generate-xcodeproj is deprecated, shown by the error message when using it:
warning: Xcode can open and build Swift Packages directly. 'generate-xcodeproj' is no longer needed and will be deprecated soon.
More information about what that is, and why its gone here.
I am replacing Parse with BackendLess on an iPhone app and when I install it via CocoaPods, I get 10 "no member named 'xxx' in the global namespace" errors in another library which is using C++ functions.
I am using Xcode 7.2 building for iOS 9.2. When I remove Backendless-ios-SDK from the Podfile and run 'pod install' again, all the errors disappear and all is well. Is there something that I can do without rewriting C++ code? Thank you
