how I can install the framework for use in Swift

[ecr334]

Please advise in detail how I can install the framework for use in Swift , the steps I have taken:

1. installed pod 'sf-proj-ios', '~> 6.0.3'.
2. created a new header file and inserted #import "sf-proj-ios-Bridging-Header.h" into it.
   now it looks like

#ifndef Header_h
#define Header_h

#import "sf-proj-ios-Bridging-Header.h"

#endif /* Header_h */
3) I press cmd+b to build the project and 22 errors appear, screenshot attached.

if I remove use_framework!
the project doesn't give these errors anymore, but when I use import sf_proj_ios and try to transform using this transformation

guard let coordinateFirst = PROJLocationCoordinate3D(coordinate: CLLocationCoordinate2D(latitude: 48.09763488, longitude: 8.58171633), andZ: 698.458) else { return }
          let proj1 = PROJProjectionFactory.projection(withAuthority: PROJ_AUTHORITY_EPSG, andIntCode: 4326, andParams: "+proj=longlat +datum=WGS84 +no_defs")
         let projEVRF : PROJProjection : PROJProjection = PROJProjectionFactory.projection(withAuthority: PROJ_AUTHORITY_EPSG, andIntCode: 4314, andParams: "+proj=longlat +ellps=bessel +towgs84=598.1,73.7,418.2,0.202,0.045,-2.455,6.7 +no_defs")
        guard let projTRANS = PROJProjectionTransform(from: proj1, andTo: projEVRF) else { return }
        print("proj-Z:", projTRANS.transform3d(coordinateFirst).z)

fatal crash.

maybe I have not enabled something in the project settings?
Also, I enabled run script for install builds only without this checkbox the project would not build with an error that it does not have access.

Try disabling modular headers for PROJ.

pod 'PROJ', :modular_headers => false

https://github.com/ngageoint/PROJ/wiki/Usage#module-headers

And you might need use_modular_headers! instead of use_framework!

[ecr334]

My podfile looks like this

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'testAppProj' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_modular_headers!
  # Pods for testAppProj

  pod 'proj-ios', :git => 'https://github.com/ngageoint/projections-ios.git', :branch => 'master'
  pod 'PROJ', :modular_headers => false
  pod 'libtiff', :modular_headers => false

end

after all manipulations the following error still appears

*** Terminating app due to uncaught exception 'Resource Not Found', reason: 'Failed to find resource 'PROJ.bundle/proj' of type 'db''

I've added the necessary files

[bosborn]

You shouldn't need to add the files since you aren't using PROJ directly (proj-ios adds them). I don't think adding them again would cause an issue but also not sure.

Here are some of our podfiles as examples (PROJ is through geopackage-ios):

• https://github.com/ngageoint/marlin-ios/blob/main/Marlin/Podfile (Swift, doesn't specify modular)
• https://github.com/ngageoint/mage-ios/blob/develop/Podfile (Obj-C & Swift, specifies modular but removes for PROJ)
• https://github.com/ngageoint/geopackage-mapcache-ios/blob/develop/Podfile (Obj-C & Swift, recently removed use_frameworks!)

With the most recent CocoaPods version, try manually cleaning and building your project.

rm Podfile.lock
rm -rf Pods/
rm -rf *.xcworkspace
pod install
open *.xcworkspace
