Thx.

Hi,
Any update on the subject ? Due to Apple updates of Xcode and timeline of updates, hope a soon update of polar sdk; if not could be annoying to update ours apps.

best regards

Any update on this issue?

[hm1205]

Hi, framework build from source as i had an unexpected free time during work time and seems to work ( both branches with or without swiftprotobuf).
i can keep on working on my app, but waiting for polar official release.
best regards

@hm1205 Can you please share the frameworks which you generated for swift 5.3, thanks

[hm1205]

@outsbook better to give you the process I've been true to build

first update Carthage version to latest version

second fix Carthage to work with swift 5.3 and Xcode 12 :

#!/usr/bin/env bash

# carthage.sh
# Usage example: ./carthage.sh build --platform iOS

set -euo pipefail

xcconfig=$(mktemp /tmp/static.xcconfig.XXXXXX)
trap 'rm -f "$xcconfig"' INT TERM HUP EXIT

# For Xcode 12 make sure EXCLUDED_ARCHS is set to arm architectures otherwise
# the build will fail on lipo due to duplicate architectures.
echo 'EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64__XCODE_1200 = arm64 arm64e armv7 armv7s armv6 armv8' >> $xcconfig
echo 'EXCLUDED_ARCHS = $(inherited) $(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT)__XCODE_$(XCODE_VERSION_MAJOR))' >> $xcconfig

export XCODE_XCCONFIG_FILE="$xcconfig"
carthage "$@"

then rebuild or build Rxswift from Carthage (using previous script) with '--no-use-binaries' ( avoid bitcode error ) and '--platform IOS' as arguments

finally run build script: build_sdk.sh

Hope will work for you. best regards

@hm1205 Thank you very much for your help, it's seems to work

[ymatt345]

I am waiting for the official update of polar-bye-sdk.
I wish to provide us soon.

[ymatt345]

Please inform us of your planned update release for Swift5.3.
All of our development efforts are suspended now.
Best regards,

@hm1205 Thanks ! It seems to work for me too. I just had to copy the generated frameworks from Carthage/Build/iOS/RxSwift.framework and 3rd_party_sdk/PolarBleSdk.framework into polar-sdk-ios and the ios example now builds and runs fine.

[Arwain]

@josephlarralde how did you get 3rd_party_sdk? When I run carthage build I get Carthage/Build/iOS/RxSwift.framework and Carthage/Checkouts/polar-ble-sdk/polar-sdk-ios/PolarBleSdk.framework.

[josephlarralde]

@Arwain to be precise, I ran ./carthage.sh update RxSwift --no-use-binaries --platform iOS, which generated the Carthage/Build/iOS/RxSwift.framework, then I ran ./build_sdk.h which generated the 3rd_party_sdk/PolarBleSdk.framework. But 3rd_party_sdk already existed anyway ... Does that help ?

[Arwain]

@josephlarralde thank you for your reply and for breaking this down! I'm with you through the initial steps, however, after I run ./carthage.sh update RxSwift --no-use-binaries --platform iOS I get the RxSwift.framework.

No ./build_sdk.h is generated. I think this is what I'm missing. What/where is this script generated?
zsh: no such file or directory: ./build_sdk.h

[josephlarralde]

@Arwain are you typing your commands from sources/iOS/ios-communications ?
Because that's where I run both scripts from.
carthage.sh is just @hm1205 's script, and build_sdk.sh (sorry just noticed the .h typo in my previous answer) is already in there.
That's also where the 3rd_party_sdk folder is, in which the new PolarBleSdk.framework will be built.
