Hi,

I am brand new to Kinvey and have just started with the iOS Swift development using Xcode 7.2.1. The Getting Started guide is very good and I followed the manual installation by downloading the latest KinveyKit framework v.1.40.7.

The framework was added successfully, bridging file is properly read but during the build, I receive 36 errors with 'Undefined symbols for architecture x86_64' and a bunch of "_sqlite3" symbol errors being referenced from KCS functions.

The complete list is attached below. What are these errors and what is the solution?

Thanks in advance.

Hi,

Thanks. Yes. After I have added it to the "Linked Frameworks and Libraries', those errors go away. But now comes new errors as copied below. Are these documented anywhere?

By the way, this error only happens when the KinveyKit framework is added manually to the project. Cocoapods installation works fine.

 

Hi Pranav,

Yes, I followed all of the manual set up process (except for the documentation installation) and it was still giving errors.

However, I found a solution on Stackoverflow that if we are getting all these linker errors, try adding the frameworks under "Target -> Info -> Compile Sources". And voila, it now works.

Again, Cocoapods installation works fine. This problem only occurs when the frameworks are added manually. I have since deleted the manual setup Xcode project and just move on with the Cocoapods version.

 

HI Pranav,

While I found a solution somewhere else, my feedback is that Kinvey's documentation is highly inadequate. I can only speak for the iOS guide, but in itself, the guide contains too many statements and examples that do not work. I have posted many forum topics on this issue, where the documentation is incorrect or incomplete. I suggest that in addition to helping out users in this forum and answer questions, can you please bring it up to the support team to re-test and overhaul the documentation? It is frustrating to have to figure things out and debug Kinvey's problems instead of working on our code.

Thanks.
