BRAOfficeDocumentPackage undeclared type

As a Beginner in swift/ios development I am currently trying to install this library https://github.com/renebigot/XlsxReaderWriter in my swift code I followed the steps indicated there for linking a bridging header to swift however BRAOfficeDocumentPackage is still an undeclared type. Is there something not clear or missing in the instructions?

Here's my attempt at a solution. I had the same problem and determinted that it was due to the bridging header not being read, and being silently skipped.

I solved it this way: wherever I had added "Release" settings, I added the same "Debug" settings.

My steps and demo project are here: https://github.com/joelparkerhenderson/demo_swift_excel_xlsx_reader_writer

I am copying my README.md here so it's searchable here.

Demo Swift Excel Xlsx Reader Writer

XlsxReaderWriter is an Objective-C library that works with Excel OpenXml files (XLSX).

To create this demo

Create a new project.

Get the repository:

git clone --depth=1 https://github.com/renebigot/XlsxReaderWriter.git 

We put the repository in the same folder as our demo project's xcodeproject:

Demo Swift Xsls Reader Writer/XlsxReaderWriter 

Add XlsxReaderWriter.xcodeproj to your project.

Add dependency:

• Targets -> Demo -> Build Phases -> Target Dependencies
• Add XslxReaderWriter -> XslxReaderWriter

Link binaries:

• Targets -> Demo -> Build Phases -> Link Binaries With Libraries.
• Add libXlsxReaderWriter.a.
• Add libz.tbd. This is more current than what the official doc says, which is to add the older version named libz.dylib.

Linking:

• Project -> Demo -> Build Settings -> Linking -> Other Linker Flags
• -> (Debug & Release) -> (+) -> Any Architeture | Any SDK
• Add: -all_load

Search Paths:

• Project -> Demo -> Build Settings -> Search Paths -> User Header Search Paths
• -> (Debug & Release) -> (+) -> Any Architecture
• Set it to: $(SRCROOT)/XlsxReaderWriter/ not $(SRCROOT)/XlsxReaderWriter/XlsxReaderWriter/.
• Select "recursive".

Bridging Header:

• Add a new file to Xcode (File > New > File), then select “Source” and click “Header File“.
• We like the file name Bridge.h
• Add this text: #import "XlsxReaderWriter-swift-bridge.h"

Add the bridge:

• Project -> Demo -> Build Settings -> Swift Compiler - Code Generation -> Objective-C Bridging Header
• -> (Debug & Release) -> (+) -> Any Architecture | Any SDK -> Add: Bridge.h

Verify:

• Run the project.
• It should compile and launch a blank simulator.

To load an Excel file

Create an Excel file by using your own Excel software, or any Excel-compatible software.

• For example, create DemoWorkbook.xlsx and save it in the repository.
• For example, in the cell A1, type the word "Alpha".

Edit ViewController.swift:

import UIKit  class ViewController: UIViewController {    override func viewDidLoad() {     super.viewDidLoad()     let documentPath: String = NSBundle.mainBundle().pathForResource("DemoWorkbook", ofType: "xlsx")!     let spreadsheet: BRAOfficeDocumentPackage = BRAOfficeDocumentPackage.open(documentPath)     let worksheet: BRAWorksheet = spreadsheet.workbook.worksheets[0] as! BRAWorksheet     let string: String = worksheet.cellForCellReference("A1").stringValue()     print(string) // The Xcode console should now show the word "Alpha"   }    override func didReceiveMemoryWarning() {     super.didReceiveMemoryWarning()   }  } 

Verify:

• Run the project.
• It should compile and launch a blank simulator.
• The Xcode console should now show the word "Alpha".
