ios – Swift package deal constructing in Xcode however not command line

I’ve a Swift package deal like:

// swift-tools-version: 5.10
// The swift-tools-version declares the minimal model of Swift required to construct this package deal.

import PackageDescription

let package deal = Bundle(
    identify: "nmbr-icu",
    merchandise: [
        .library(name: "nmbr-icu", targets: ["nmbr-icu"])
    ],
    targets: [
        // Main NMBR target, contains 1 ObjC++ file (h + mm)
        .target(name: "nmbr-icu",
                dependencies: ["ICU"]),
        // Goal to construct the ICU framework, an xcframework for the ICU C++ code
        .binaryTarget(identify: "ICU",
                      path: "./ICU.xcframework"),
        // Take a look at goal
        .testTarget(identify: "nmbrTests", dependencies: ["nmbr-icu"])
    ],
    cxxLanguageStandard: .cxx20
)

The challenge construction appears like:

Once I open this package deal (in Xcode – by double-clicking the Bundle.swift file) I can construct (CMD+B) and take a look at (CMD+U). Nevertheless, operating swift construct returns an error saying that one of many header information in my xcframework can’t be discovered:

NMBRFormatter.mm:11:10: deadly error: 'unicode/unistr.h' file not discovered
#embody <unicode/unistr.h>

What am I lacking? The repo is open supply right here: https://github.com/kerrmarin/nmbr-icu
