Objectmapper: Invalid Redeclaration Error with Swift 4.x & Xcode 10 Beta

[anilabsinc-ajay]

Hi Team,
That's called a great start with Xcode 10 beta. Now there is no warning for Invalid Redeclaration, instead, it shows Error...

[dispatchMain]

Changing Swift version to 3 does not make it compile either; neither does changing back to legacy build system. It fails in all conditions.

[anilabsinc-ajay]

Any Plan to resolve this issue or I have to move back to Xcode 9.4

[alecdoconnor]

I have created a PR at https://github.com/Hearst-DD/ObjectMapper/pull/978 to hopefully fix this issue. I noticed, after creating it, that another PR exists which has failed tests. Hopefully this produces the right results!

Try commenting out duplicate declarations and compile. It worked for me. And in implementation, use only one type of method call. It is a temporary solution. We need to wait anyways, till we get a fix.

[alecdoconnor]

Hi @harisworld21
that is a working solution, the PR has removed these lines of code to conform to Swift Evolution's SE-0054 Abolish ImplicitlyUnwrappedOptionals

[anilabsinc-ajay]

@alecdoconnor Need a solution that should work on both xcode 9 and 10

[gcharita]

I tried my best to support both Xcode 9 and 10 beta in pull request #980 .

Invalid redeclarations removed from swift 4.2 and above. This means that the warnings in Xcode 9.3 and 9.4 will remain. (invalid redeclarations when removed in swift 4.1 causes some tests to fail)

I even added support for Xcode 9.2 (compactMap)

Hope this helps.

Is there any timeline to be getting a fix in for this? I would like to be moving forward using Xcode 10 to prep for iOS 12, however, this is making it so I cannot even compile our main app. Thanks in advance!

[alecdoconnor]

Hi Josh! Feel free to contribute to the PRs to help us get closer to a working build. I believe there were two (the last time that I checked) that technically work, so you would be able to check the branch out directly into your project.

[anilabsinc-ajay]

@alecdoconnor Are you planning any timeline for this.

[alecdoconnor]

No, because I am not the maintainor of this repository.

Aren't these warnings simply because one implementation of the function is marked for specific versions of Swift and the other is not?

i.e. just add the following to the other implementation and the warning goes away:

#if (swift(>=4.1.50))

@tristanhimmelman Any Plans to update This awesome mapping library for iOS

[gcharita]

@anilabsinc-ajay this issue has already been fixed in version 3.3.0. Just download the latest version.

[LeoSnek]

I'm using 3.3.0 and I'm getting these warnings.

[gcharita]

@staz1000 I am not getting any error in an Xcode 10 project with version 3.3.0.
Maybe you should run a clean or delete DerivedData.

[wudijimao]

Update to 3.3.0 is OK!!!!!
pod update ObjectMapper

[wudijimao]

Any way, The document maybe need to update~ It still suggest us to use ver 3.2.0~

[tristanhimmelman]

The README has been updated with v3.3.0.
