Symbol(s) not found for arm64

It might help to post the build transcript that shows the tool invocation line(s) and any other logged errors or messages. (You can edit out any sensitive path components before posting, if necessary.)

>> I can't detect any changes that may have triggered this condition

Newer versions of Xcode change the set of hardware architectures that are supported, so existing projects can fail, sometimes just because you used to be building for an architecture that you never used.

"..post the build transcript.." Do you mean this:

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Yep, that was what I meant. 🙂

So, the problem is nothing to do with architectures (I think), but rather than not everything is being linked because of these search path errors:

ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Library'

ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Release-iphoneos'

ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Debug-iphoneos'

While it's possible that your project contains search paths that aren't actually used, it looks like this build depends on the product of another build target in the same project (.../build/Release-iphoneos and .../build/Debug-iphoneos). It's also odd that both the debug and release products are linked against.

So, my guess is that your projects search path settings are messed up, possibly in multiple ways. One thing to keep in mind is that when you tell xcode to link (say) an app against libraries or frameworks built in the same project, you typically want the library be reference to be in the "relative to build products" form. (You can adjust the referencing form via the File attributes inspector.) It looks like you might have (inadvertently or intentionally) added both debug and release paths explicitly to get around the issues that the wrong file referencing form would give you.

Sorry, it's hard to be specific, because it's hard to describe a project structure in any detail, in a forum post like this.

How annoying that the reported error related to architectures, but may be a complete red herring!

As you may have guessed, this is a project that I have inherited (from a departed predecessor) so I haven't been in on the earlier development.

I have not made any changes to the build settings since the earlier working version, so the ref's to missing items:

"ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Library'

ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Release-iphoneos'

ld: warning: directory not found for option '-L/Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Debug-iphoneos' "

Is very odd.

And they were "only" warnings, so do you really think that's the problem, or something more obscure???

>> do you really think that's the problem

It certainly very, very suspicious. The link fails because the linker doesn't find all the object files, and paths that are supposed to be searched for object files don't exist. It's almost a chain of evidence, but not quite.

Whether or not that's the problem, I think your first duty is to eliminate the condition that leads to these messages.

I agree, but sadly don't have the experience to do it. 😟

There certainly isn't a directory "Users/alansmith/Documents/raceQs-iOS/ios/raceqs_pod/Library" (and I don't hink ever has been).

Nor do I know where the reference to that directory might be found in my Xcode project.

The reference to "Library" in the missing missing directory path is odd as I don't think there are any files in the app other than the application code ( Obj-C and Swift) and the Pods.

Any assistance would be greatly appreciated to squish this.

The place to start is your list of undefined symbols. Pick one, say the class "DLAVAlertView". What target/module/file/library/framework is the defined in? How does the project look like it intended to include this in the link? (For example, is it in the list of libraries and frameworks to link against, in the Info tab of the project editor for the target being built?) Or is it in a Build Phase that looks manually created? Is there a project item for it, and what does the Files inspector say about its path and/or referencing style?

Once you've solved one, you'll presumably know what to fix for the others.

I really appreciate your perserverence.

In the case in point, DLAlertView (as are all the objects reported as missing in the error report) is an external library (in my Podfile) referenced in a few of the (legacy) Obj-C files.

It is imported as

#import "DLAVAlertView.h"

and referenced in the application code like, for example:

'DLAVAlertView *alertView = [[DLAVAlertView alloc] initWithTitle:@"Please specify mark name" message:nil delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil, nil];

The code compiles and runs on theSIM and a real device, so the library must be correctly referenced.

As I said, it only gets reported as an error when I go to build an Archive.

You're on your own with podfiles. 🙂

The problem (from the point of view of these forums) is CocoPods is its own ecosystem, and how it integrates into Xcode is its problem, not Xcode's.

I wish I had better news for you.

Just one more shot before you throw me to the wolves!

As a newbie, I can't understand how a successful build for the Sim or a device can fail in a build for an Archive.... How are they different????

> How are they different????

Along with alternate signing/profiles, archiving adds a layer of (pre) store checks that aren't included with debug/dev (vs. dist) builds.

All in all, it is a non-trivial process that requires patience and sticktoittiveness by the bushel 🙂

Good luck.

Using xCode Version 10.0 beta 4 (10L213o) trying to Archive - we got the same error.

The project using Swift 4 runs fine on Simulators and iPads.

Try to go to Project Settings and use: Legacy Build System.
