I'm creating a static library in iOS using Objective-C. This library will gather data from the app where this library is integrated, the gathered data from the app will be sent to the server.
I'm just wondering if is it possible to embed a cocoa pods framework in my library like AFNetworking?
Thanks in advance
Yes. It seems to be possible.
I created a static library project and tried to integrate cocoapods in to it with below steps.
pod init
Then edited the podfile to integrate AFNetworking pod in the project like below
# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
target 'Testing' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
pod 'AFNetworking', '~> 3.0'
# Pods for Testing
end
then gave
pod install
I get the below warning
[!] The Podfile contains framework or static library targets
(Testing), for which the Podfile does not contain host targets
(targets which embed the framework). If this project is for doing
framework development, you can ignore this message. Otherwise, add a
target to the Podfile that embeds these frameworks to make this
message go away (e.g. a test target).
As the first line in the warning says we are doing framework development, hence we can ignore this message and it should work fine.
Also my suggestion is to use Alamofire instead of AFNetworking as Alamofire is swift based and AFNetworking is objective-c based.

I would like to create a framework that is archived and distributed on its own. The problem I'm having is that I would like this library to have cocoa pod dependency libraries compiled into it. Is this possible?
It seems to work. But when I embed the framework in a sample app and invoke code of the embedded dependency I get an error: dyld: Library not loaded:... Reason: image not found
# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
target 'MySDK' do
use_frameworks!
pod 'ALBNoSQLDB', '~> 4.2'
end
Do I have to run an archive script to embed the dependent pods? Is this even possible?
Thanks.
I am doing Objective-C in iOS app. But the problem is I want to add few Objective-C apis into that I added successfully earlier with cocoa pods, But, now I want to add Swift Api through cocoa pods, but the problem getting while installing is following.
[!] Pods written in Swift can only be integrated as frameworks; add use_frameworks! to your Podfile or target to opt into using it. The Swift Pods being used are: apis
But I can't add this manually due to its large api and it contains sub folders.
But, if I remove "#" key from use_frameworks!, its getting installed, but, the old Objective-C apis getting file not found in my project.
Even I have very basic knowledge at installing frameworks/apis through cocoa pods.
Can any one suggest me how to over come this.
use_frameworks! will work with Objective-C pod only if they are dynamic frameworks not static libraries. Most of the popular third party libraries are using dynamic frameworks like AFNetworking, GoogleMaps etc.
Make sure all your Objective-C pods are dynamic frameworks. If you are not sure just create a sample project with cocoapods and use use_frameworks!. Try adding one by one, all the pods and find out which one is the culprit.
I had that problem once, what I did was use use_frameworks! like you mentioned, and then I changed how the Objective-C imports are written.
The command use_frameworks! turns each pod into a Framework, so in your projects the .h and .m files are no longer visible to the import like they would usually.
As a result, instead of using for example #import <AFNetworking/AFNetworking.h>, you do #import AFNetworking;
From my own experience, and maybe it was just a special case for my project. But turning everything into frameworks slowed down the compile time on Xcode and it made my App Package bigger for some reason.
Podfile file:
platform :ios, '10.0'
use_frameworks!
def pods
pod 'Alamofire', '= 4.4'
pod 'SwiftyJSON' '= 3.1.4'
pod 'MBProgressHUD'
end
target 'YourProject' do
pods
end
YourProject-Bridging-Header.h
#import <MBProgressHUD/MBProgressHUD.h>

Our code structure is as follows,
We have a Framework A for iOS , which Application going to link and embed as a link as a binary inside Xcode,
Framework A pod file is
target 'iosFramework' do
# Uncomment this line if you're using Swift or would like to use dynamic frameworks
use_frameworks!
# Pods for iosFramework
pod 'Firebase'
end
Now in the 'Application' where i am going to include 'iosFramework' i am getting error "FirebaseInstanceId" cannot be found,
Any help,
Basically i wanted to know, Is this correct way to make use of pod ?
What should be ideal practice if the code structure is something like this,
I am on Xcode 7.3 and pod 1.0.1
I'm creating a new Cocoa Touch Framework (MyFramework.framework), which will have a dependency on Alamofire. This framework will be written in Swift. As a test I started a new Cocoa Touch Framework project:
File > New > Project > Framework & Library > Cocoa Touch Framework
Then, in the terminal I performed:
pod init
under this projects directory. In the newly created Podfile I added the following:
source 'https://github.com/CocoaPods/Specs.git'
# Uncomment this line to define a global platform for your project
platform :ios, '8.0'
# Uncomment this line if you're using Swift
use_frameworks!
pod 'Alamofire', '~> 3.0'
Once again, in the Terminal I performed:
pod install
and started coding away.
Everything seemed well and good till I used the MyFramework.framework Product in a Single View Project. When I attempt to run the project I get the following issue:
dyld: Library not loaded: #rpath/Alamofire.framework/Alamofire
Referenced from: /Users/me/Library/Developer/CoreSimulator/Devices/87DA70B6-49BF-441E-BD81-F4A80B0792CF/data/Containers/Bundle/Application/2E414EA8-7E54-4D71-9295-566D4FAAADE2/test.app/Frameworks/MyFramework.framework/MyFramework
Reason: image not found
I thought that Cocoa Touch Framework projects were inherently Dynamic, and therefore would include all dependencies.
Can anyone tell me why this is happening and how I may be able to fix it?
Is this an issue with CocoaPods or am I missing something?
I'm a noob to Stack Overflow so please let me know if you need more information from me.
Thanks!
Unfortunately CocoaPods doesn't support use with Cocoa Touch Framework target. I found a few references to this while digging through their issues on GitHub:
We don't really support integrating Pods into framework targets...
-neonichu on Nov 4, 2015
and
...in order for this to "just work", CP would need to do a recursive analysis of dependencies in your Xcode project and also somehow ensure that you would never use the build product in another context.

So far I've found two ways to deal with the issue:
The right way is to create a new pod spec for your framework and bring it in to your main project via CocoaPods. This resolves all of the problems CococaPods has with the dependency graph and is the recommended solution from the CocoaPods developers.
The easy way is to include the pods from your framework in your main project. This seems to work, but frankly I don't know why. This is the Podfile from my test project:
platform :ios, '9.0'
use_frameworks!
def myfirstframework_pods
pod 'Alamofire', '~> 3.0'
end
target 'MyApp' do
pod 'SwiftKeychainWrapper', '~>1.0'
myfirstframework_pods
end
target 'MyFirstFramework' do
myfirstframework_pods
end
Try adding the dependency on Alamofire in the framework's podspec as below
Pod::Spec.new do |s|
# Other setup
# Dependencies
s.dependency "Alamofire"
# Other dependencies if any
I have just started a new Swift project and I would like to use different libraries. In particular, I would like to use Realm.io, an Obj-C library. But, I would also like to use pure Swift libraries such as Alamofire or Dollar.
I use Cocoapods for managing my dependencies. I use the latest version (0.37.0) and the new use_frameworks! flag. pod install is successful anytime.
Unfortunately, when I try to build my project I get two errors (for my main target):
Umbrella header Realm.h not found from module.modulemap
Could not build Objective-C module Realm from any file using import Realm
Other imports work fine.
I have noticed the following: if I remove pure Swift libs and use_frameworks, everything works fine. I am aware about this current issue from Cocoapods. However, it should not be a problem for Realm asks developers to use that flag.
Here is my Podfile:
platform :ios, '8.0'
use_frameworks!
target 'rothrock' do
pod 'Realm'
pod 'Cent'
pod 'SwiftyJSON'
pod 'Alamofire'
end
target 'rothrockTests', :exclusive => true do
end
I use no bridging header. Should I?
Any idea or workaround?
Alright, here is the full walkthrough:
Install dependencies using Cocoapods and the use_frameworks! flag.
As you need to use a Objective-C dependency, create a Bridging header. You can create one easily by importing an Objective-C class to your Swift project, than remove it (the wizard should ask you if need a bridging header). Otherwise, create a new header file. Then, navigate to your target configuration and enter the name of your file in Swift Compiler - Code Generation > Objective-C Bridging header.
Still in your target configuration, add a new entry in Search Paths > User Header Search Paths: Pods as value and flag it as recursive.
Remove any import instruction from your code, relative to your Objective-C library.
Build your project. You should have a success.
You need a bridging header and import your Objective-C library headers there.
If you are using only Realm you can check out this documentation for Swift http://realm.io/docs/cocoa/ (go to CocoaPods down in the tabs)
Swift
Install CocoaPods 0.36.0 or later ([sudo] gem install cocoapods).
In your Podfile, add use_frameworks! and pod 'Realm' to your app target.
From the command line, run pod install.
Use the .xcworkspace file generated by CocoaPods to work on your project!
Download the latest release of Realm and extract the zip.
Drag the file at Swift/RLMSupport.swift into the File Navigator of your Xcode project, checking the Copy items if needed checkbox.
I just installed the Realm library in a project I have with some of the libraries you mention above like Alamofire and SwiftyJSON and others and it works fine when you build the project and even put the import Realm, no compilation errors at all.
I'm using Cocoapods 0.36.0, the stable version and this is my PodFile :
source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!
platform :ios, '8.0'
link_with 'ApiWorkflow', 'ApiWorkflowTests'
pod 'SwiftyJSON', '~> 2.2'
pod 'Alamofire', '~> 1.2'
pod 'Typhoon', '~> 3.0'
pod 'SwiftCSV', '~> 0.1'
pod 'Realm'
I hope this help you
